Specification forming part of Letters Patent N o. 55,289, dated June 5, 1866,

To all whom it may concern:

Beit known that I, THOMAS HANSON, of the city, county, and State of New York, have invented a new and useful Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in wl1ich i Figure l is a front elevation; Fig.v 2, a vertical section and Fig. 3, another section, on a larger scale, taken at the line A a of Fig. 2.

The same letters indicate like parts in all the figures.

The object of my invention is to. operate pumps at great distances from the locality of the motive power 5' and to this end my said invention consists in interposing a column or columns of water between the pistons working in separate cylinders with suitable valves, one cylinder being located near to and its piston operated by the motor, and the other x near the place from whence the water is to be pumped.

In the aecompanyin g drawings, A represen ts a cylinder with a piston, b, fitted to work therein, the piston-rod c of which receives motion by a connecting-rod, d, from a crank, e, operated by a steam-en gine or other suitable lnotor. There are two side pipes, ff', one on each side of and each communicating` by two nozzles, g g, with opposite ends of the cylinder, and provided with induction and eduction valves of any suitable construction.

Near the place from whence water is to be pumped-say the bottom of a mine-is located a reciprocating pump, B, of any suitable construction, such as represented in the accompanying drawings, and having` an inductionpipe, h, and an eduction-pipe, z', extending up to the surface, or wherever the water is to be discharged. This pump is to be providcd in any of the known modes with suitable induction and eduction valves. l

The piston-rod j of the pump is of such length as to be attached to a piston, lr, adapted to work in the cylinder of a water-engine, (l, placed in line with the pump-cylinder.

The water-engineCis provided with a waterchest, l, which communicates by two separate pipes, m m', with the side pipes, f f', of the cylinder A 5 and the said water-chest communicates by suitable posts u a with both ends of the cylinder, and it is provided with slide- 'The cylinder A and the cylinder of the4 water-engine C should be of equal capacity, and before starting the said cylinders the side pipes, water-chest, and connecting-pipes in m should be entirely illed with water. In that condition, as the piston in the cylinder A is moved in the direction of the arrow, the water below it is forced through the nozzle g, side pipe, f, and connecting-pipe m, and thencev through the water-chest and valve-port into oneI end of the cylinder of the engine C, thereby acting against and forcing the said piston to the opposite end of its cylinder. In the meantime the water which was contained in the cylinder of engine C Hows out through the valve-port, water-chest, connecting-pipe m', side pipe,j", and nozzle g, into the opposite end of the cylinder A.

In this way, by the working of the piston in the cylinderA alternately in opposite directions, the water interposed between that piston and the piston of the engine C impels the engine, imparting to thepiston thereof a reciprocating motion, which operates the pump-piston connected-therewith, and such will be the result whatever may be the distance between the water-engine and the piston operated by the mot-ive power.

The above arrangement will be found useful and economical in many localities, and particularly in pumping mines ofcousiderable depth, where the steam-engine or other motor, for obvious reasons, must be on the surface.

What I claim as my invention, anddesire to secure by Letters Patent, is-

Giving the required reciprocating motion to a pump or pumps for raising water by means of pistons workingin separate cylinders, and having water or other non-elastic fluid interposed as a medium for communicating the motions, substantially as described.

THOMAS HANSON.
